<p>Enzootska leukoza goveda je maligna virusna neoplazma retikulohistiocitarnog sistema&nbsp;progresivnog karaktera, koja se karakteri&scaron;e intenzivnim razmnožavanjem limfocita. Ova&nbsp;bolest govedarstvu nanosi velike materijalne &scaron;tete dovodeći do visokog nivoa mortaliteta,&nbsp;pojave učestalijih oportunističkih infekcija, smanjenja produktivnosti i reprodukcije na&nbsp;leukoznim farmama. Imajući u vidu, da govedarstvo predstavlja strate&scaron;ku granu u stočarstvu&nbsp;Srbije i učestvuje u stvaranju znatnog dela nacionalnog dohotka od 1999. godine,&nbsp;preduzimana su sistematska dijagnostička ispitivanja ra&scaron;irenosti ELG na farmama goveda&nbsp;kako u intenzivnoj tako i od 2000. godine i u ekstenzivnoj proizvodnji goveda. Kori&scaron;ćene su&nbsp;savremene metode dijagnostike ELG najpre agargel-imunodifuzioni test (AGID), a potom i&nbsp;indirektna imunoenzimska metoda (ELISA) kao dijagnostički test izbora. Na osnovu&nbsp;dobijenih epizootiolo&scaron;kih podataka sprovo&ntilde;ene su mere za suzbijanje i iskorenjivanje EGL na<br />farmama goveda. U zavisnosti od tehnolo&scaron;kog procesa proizvodnje, kao i od ekonomskih&nbsp;mogućnosti farmi sprovo&ntilde;eni su različiti modeli kontrole i eradikacije.<br />ELG predstavlja veoma ozbiljan zdravstveni i ekonomski problem za govedarsku<br />proizvodnju posebno za zapate mlečnih goveda, a po&scaron;to se i pored sprovo&ntilde;enja mera za&nbsp;eradikaciju, leukoza jo&scaron; uvek zadržala u nekim na&scaron;im stadima i zapatima goveda smatrali smo&nbsp;da bi trebalo preispitati dosada&scaron;nju strategiju kontrole ELG.<br />Razmatrane su pote&scaron;koće u sprovo&ntilde;enju mera za suzbijanje i iskorenjivanje leukoze goveda&nbsp;kao i potreba za izučavanjem epizootiologije, odnosno kontrole kretanja leukoze u&nbsp;trakozvanim leukoznim zapatima koji predstavljaju potencijalne izvore &scaron;irenja leukoze.&nbsp;Imajući u vidu navedeno, cilj ovog ispitivanja je bio ustanoviti stepen ra&scaron;irenosti ELG i&nbsp;ispitaju do sada kori&scaron;ćeni programi kontrole i eradikacije oboljenja. Zadaci ovog istraživanja&nbsp;su bili da se ispitaju pogodnosti pojedinih dijagnostičkih metoda u cilju postavljanja rane&nbsp;dijagnoze oboljenja, istražiti incidenciju i prevalenciju bolesti, proceniti značaj pojedinih&nbsp;puteva preno&scaron;enja u okviru farmi i u regionu, izvr&scaron;iti analizu dosada&scaron;njih rezultata borbe i&nbsp;evaluaciju pojedinih modela, predložiti najpogodnije modele kontrole bolesti u cilju potpune&nbsp;eradikacije bolesti, a tako&ntilde;e razviti i adekvatan model nadzora bolesti kako bi se sprečila&nbsp;njena ponovna pojava i &scaron;irenje. Rezultati serolo&scaron;kih ispitivanja pokazuju da je otkriveno 10.181 pozitivnih životinja, odnosno 8,1% posto životinja u zapatima goveda na velikim farmama. Epizootiolo&scaron;ka situacija na farmama goveda individualnog sektora zahtevala je posebnu pažnju i tu je ispitano 281.369 uzoraka krvi goveda i otkriveno je 567 pozitivnih grla ili 0,4% posto na području 12 op&scaron;tina. Rezultati seroprevalencije predstavljali su ključnu informaciju od značaja za izbor modela kotrole ELG. Odnosno istraživanje efikasnosti pojedinih modela u postizanju rezultata i&nbsp;zadatih ciljeva. Značajnih za izradu komparativne analize kori&scaron;ćenih modela, njihove primene i evaluacije. Epizotiolo&scaron;ki modeli su analizirani, izvr&scaron;ena je njihova evaluacija i preporuka za primenu u epizootiolo&scaron;koj praksi.&nbsp;</p> / <p>Enzootic bovine leucosis is viral malignant neoplasm reticulohistiocytic system and has&nbsp;progressive character, which is characterized by intensive multiplication of lymphocytes.&nbsp;This disease is causing a great material damage to cattle farming, leading to high level of&nbsp;mortality, with the emergence of more frequent infections and a reduction in productivity&nbsp;and reproduction in farms in which the leukosis appeared. Having in mind that the cattle&nbsp;farming is a strategic branch of the Serbian livestock and participates in the creation of a&nbsp;significant part of the national income since 1999, systematic diagnostic tests of the&nbsp;prevalence of EBL were undertaken on cattle farms, both in the intensive cattle production&nbsp;and from 2000 extensive production. Modern diagnostics methods of EBL were used,&nbsp;firstly the agargel-immunodiffusion test (AGID), followed by an indirect enzyme&nbsp;immunoassay method (ELISA) as well as a diagnostic test of choice. Based on the&nbsp;obtained epizootic data, the measures for the control and eradication of EBL were carried&nbsp;out on cattle farms. Depending on the technological process of production, as well as the&nbsp;economic farm opportunities, different models of control and eradication were&nbsp;implemented.<br />EBL is a very serious health and economic problem for cattle farming, especially for<br />dairy cattle herds, and despite the implementation of the measures for the eradication of&nbsp;the disease, leucosis is still held in some of our flocks and herds of cattle. Because of that&nbsp;we thought that the current control strategy EBL should be examined.<br />The difficulties in implementing measures to suppress and eradicate bovine leukosis were&nbsp;discuses and the requirement to study the epizootiology , as well as to control the&nbsp;movement of leukosis in so-called leukostic herds, that represent potential source of&nbsp;spreading the leukosis.<br />Taking into account, the purpose of this study was to establish the degree of<br />prevalence of EBL to examine the programs that were used so far to control and eradicate&nbsp;the diseases. The task of this study was to examine the benefits of specific diagnostic methods in order to establish early diagnosis of the diseases, to see into the incidence and prevalence of the leukosis, to estimate the significance of some routes of transmission within the farm and in the region, and to carry out an analysis of recent results in fighting and evaluation of individual models, to suggest the most appropriate models of disease control in order to complete the eradication of leukosis, but also to develop an adequate model of disease control to prevent its re-emergence and spread. The results of serological tests indicate that 10.181 the positive animals were detected, or 8.1 % percent of the animals in cattle herds in large farms. Epizootiological situation in the cattle farms of individual sectors required special attention and 281.369 blood samples of cattle were examined and the 567 positive cases were discovered, or 0.4 % percent in&nbsp;12 communities. Results of seroprevalence were a key information for the choice of models to control ELG, or to investigate the efficiency of some models to achieve results and goals, and important for the production of comparative analysis of models that were used, their implementation and evaluation. Epizootic models were analyzed, their evaluation was made and recommendations for their implementation in the epizootic practice.&nbsp;</p>

Introdução - A esquistossomose é uma parasitose de grande relevância para a saúde pública. O Estado de São Paulo tem um perfil de baixa endemicidade, com transmissão focal. A região do Vale do Ribeira é uma das principais áreas endêmicas do Estado, e desde a década de 1980 se investiu muito em controle e vigilância da esquistossomose, principalmente em Itariri e Pedro de Toledo. Apesar dos esforços, verifica-se que antigas coleções hídricas com moluscos parasitados permanecem na região. Aspectos relativos ao hospedeiro intermediário da região suscitam considerações sobre os efeitos da infecção parasitária sobre sua biologia. Objetivos - Avaliar os dados de controle e vigilância do hospedeiro intermediário, em municípios do Vale do Ribeira, e observar os efeitos da infecção parasitária em Biomphalaria tenagophila de Itariri. Metodologia - Foram levantados dados epidemiológicos da esquistossomose, do período de 1981 a 2006, e dados das pesquisas planorbídicas, do período de 1997 a 2006, em municípios do Vale do Ribeira. Um estudo experimental foi conduzido para verificar os efeitos da infecção parasitária em espécimes de Biomphalaria tenagophila, procedentes de Ana Dias, Itariri. Delineamento experimental: 69 moluscos da geração (P) de laboratório formaram grupos controles e experimentais. Os moluscos experimentais se submeteram à infecção com 10 miracídios do Schistosoma mansoni - linhagem SJ. Variáveis observadas: fecundidade, mortalidade, tamanho e eliminação de cercárias. Análise histológica foi realizada em moluscos parasitados para verificar os efeitos da infecção. Resultados - constatou-se que nos últimos 10 anos Itariri, Pedro de Toledo e Miracatu continuam sendo os principais municípios com importância epidemiológica para esquistossomose. Pesquisa planorbídica: houve um aumento das coleções hídricas com presença de moluscos parasitados, em Itariri, e diminuição em Pedro de Toledo; houve um aumento na taxa de infecção dos moluscos de Itariri e Pedro de Toledo, nos últimos cinco anos; Infecção experimental: foram observados nos moluscos infectados, deformação nas conchas, maior mortalidade e diminuição da fecundidade na fase patente; a taxa de infecção foi de 59 %. O exame histológico revelou presença de esporocistos secundários e cercárias. Concluiu-se que houve uma evolução no potencial de riscos de transmissão da esquistossomose, em vários municípios do Vale do Ribeira, especialmente nos municípios de Itariri e Pedro de Toledo, que aliada à adaptação existente entre hospedeiro e parasita poderá levar a um aumento da transmissão do Schistosoma mansoni. Recomenda-se um trabalho de vigilância epidemiológica integrado com SUCEN e grupos técnicos da VIGILÂNCIA EPIDEMIOLÓGICA do Vale do Ribeira. / Introduction - Schistosomiasis is a parasite with great importance for public health. The São Paulo State has a low endemicity profile, presenting some local focuses of the disease. The Ribeira Valley is one of the main endemicity areas in the State and, since the 1980's, a great deal has been invested in the control and surveillance of Schistosomiasis, particularly in the Itariri and Pedro de Toledo areas. In spite of efforts, old-established hydric collections with parasite-infected molluscs remain in the region. Aspects related to the intermediate hosts found in the region have taken us to considerations about parasitary infection effects in hosts' biology. Objectives - Evaluate the control and surveillance data of the Schistosomiasis intermediate host in the Ribeira Valley districts and observe the parasitary infection effects on the Biomphalaria tenagophila in the Itariri region. Methodology - Survey of Schistosomiasis epidemiological data, between 1981 and 2006, and survey of planorbidic research results, from 1997 to 2006, in the Ribeira Valley. Experimental work to assess the effects of parasitary infection on Biomphalaria tenagophila, from Ana Dias, Itariri. Experimental criteria: 69 laboratory-generated individuals (P) were employed to form control and experimental groups. The experimental molluscs were infected with 10 Schistosoma mansoni strains ("miracidias") - from the SJ lineage. Observed variables: fecundity, mortality, size and cercarie elimination. Histological analysis of parasite-infected molluscs to assess the infection effects. Results - Itariri, Pedro de Toledo and Miracatu have remained as the main Schistosomiasis epidemiological-importance centres in the last ten years. Planorbidic research: increase of hydric collections with the presence of parasite-infected molluscs, in the Itariri region, and decrease of it in the Pedro de Toledo region. Increase in molluscs' infection rate, in the Itariri and Pedro de Toledo regions, in the last five years. Experiemental infection: shell deformation, higher mortality rate, fecundity-capacity reduction were observed in the infected molluscs in the patent phase. It was observed a 59 %-infection rate. The histological study showed the presence of secondary sporocysts and cercaries. This leads to the conclusion that there has been an increase of Schistosomiasis' transmission risk in several Ribeira Valley districts, particularly in the Itariri and Pedro de Toledo regions, which allied to the parasite's and host's adaptation capacity, may lead to Schistosoma mansoni transmission. It is recommended that articulated efforts between the SUCEN and EPIDEMIOLOGIC-SURVEILLANCE technical groups are implemented in the Riberia Valley.

Europos Sąjungos valstybių narių bendradarbiavimas sienos apsaugos sektoriuje / The protection of European Union countries- members in the sector of border guard

Dainiuvienė, Toma 05 July 2011 (has links)
Sienų apsauga yra aktuali tema bet kurioje pasaulio valstybėje. Tenka pastebėti, kad kuomet valstybė turi išorines sienas su kitomis valstybėmis, ji turi sukūrusi politiką, teisinę bei institucinę bazę sienos apsaugai, užtikrinančiai tos valstybės gyventojų socialinius, politinius, teisinius, ekonominius, kultūrinius, mokslinius interesus. Europos Sąjungos sienos apsaugos srityje, išskiriamos dvi sienų sąvokos – vidaus bei išorės sienos. Valstybių narių bendradarbiavimas, pagrįstas integruotos išorinės sienos apsaugos koncepcija, orientuotas į valstybių narių bendras pastangas, siekiant užtikrinti ES vidaus saugumą, vykdant sienos kontrolę, ją saugant bei bendradarbiaujant vykdant įvairias operatyvines operacijas bei bendrus projektus. Darbo tikslas – išanalizuoti ES valstybių narių bendradarbiavimo sienos apsaugos srityje gaires bei įvertinti bendradarbiavimo efektyvumą. Darbą sudaro įvadas, kuriame pateikiamas temos aktualumas, analizuojama problema, keliamas tikslas bei uždaviniai, pateikiami tyrimo metodai, trys dėstomosios dalys bei išvados ir pasiūlymai. Darbe remiantis jau atliktai tyrimais, taip pat Šengeno teisynu, Amsterdamo sutartimi, Europos Ekonominės Bendrijos steigimo sutartimi, Lisabonos sutartimi analizuojamos ES valstybių narių bendradarbiavimo sienos apsaugos srityje gairės, išskiriamos problemos, vertinamas bendradarbiavimo efektyvumą. / Border guard, control and surveillance are a relevant topic in every country. It should be mentioned, that when the country has borders with other countries, it has created the policy, legal and institutional basis for the control and surveillance of its border that secures social, political, legal, economical, cultural and scientific interests of the citizens of that country. There are two border concepts in the European Union – internal and external borders. The co-operation of the member states, based on the integrated border management concept, is oriented to the common attempt to control and secure the external border carrying out various joint operations and projects. The purpose of this paper is to analyse the guidelines of the cooperation of the EU member states in the field of external border guard and to evaluate the effectiveness of this cooperation. This paper consists of preface, where the relevance, problem, purpose, objectives are presented, three main parts, conclusions and appendixes. The analysis of the guidelines of cooperation of the EU member states in the field of external border surveillance and evaluation of the effectiveness of this cooperation is being carried out using the researches, Shengen acquis, the Treaty of Amsterdam, the Treaty of Rome, the Treaty of Lisbon, etc.
